Application technology eng<strong>in</strong>eer<br />
Jérôme Quet was born on 07.05.<br />
1976 and has been work<strong>in</strong>g with<br />
SCHERDEL <strong>in</strong> Beauvais s<strong>in</strong>ce<br />
June 2004.<br />
In addition to assist<strong>in</strong>g with the<br />
diversification of the range of<br />
products, he is ma<strong>in</strong>ly <strong>in</strong>volved <strong>in</strong><br />
the development of new process<br />
technologies at the location <strong>in</strong><br />
Beauvais.<br />
This also <strong>in</strong>cludes product development<br />
with the appropriate <strong>in</strong>dustrialization<br />
and the realization of<br />
improvement methods (5S etc.)<br />
with project handl<strong>in</strong>g (APQP). As<br />
application technology eng<strong>in</strong>eer<br />
he is also <strong>in</strong>volved <strong>in</strong> the control<br />
and monitor<strong>in</strong>g of plans for measures<br />
relat<strong>in</strong>g to production equipment<br />
and <strong>in</strong>vestments, and therefore<br />
has a decisive <strong>in</strong>fluence on<br />
rationalization measures and the<br />
reorganization of production divisions.<br />
Mr Quet is unmarried but lives <strong>in</strong><br />
a domestic partnership. His hobbies<br />
are music (he is a keen<br />
drummer), swimm<strong>in</strong>g and mounta<strong>in</strong><br />
bik<strong>in</strong>g. In addition to play<strong>in</strong>g<br />
badm<strong>in</strong>ton <strong>in</strong> a club he is also <strong>in</strong>terested<br />

New ultrasonic clean<strong>in</strong>g<br />
<strong>in</strong>stallation <strong>in</strong> Beauvais<br />
Record level <strong>in</strong> cleanl<strong>in</strong>ess requirements<br />
I<br />
n order to satisfy the <strong>in</strong>creas<strong>in</strong>g customer<br />
demands <strong>in</strong> relation to the<br />
quality and cleanl<strong>in</strong>ess of technically<br />
sophisticated components, the<br />
SCHERDEL subsidiary, Herckelbout<br />
Dawson, has <strong>in</strong>vested <strong>in</strong> a new clean<strong>in</strong>g<br />
<strong>in</strong>stallation at their location <strong>in</strong><br />
Beauvais, France. The components<br />
are treated by an ultrasonic process<br />
and also with a detergent. This state-ofthe-art<br />
<strong>in</strong>stallation has a special monitor<strong>in</strong>g<br />
system permitt<strong>in</strong>g traceability of<br />
the components. Defective products<br />
can be reliably identified dur<strong>in</strong>g the<br />
production process, thus avoid<strong>in</strong>g<br />
problems with the customer.<br />
Cleanl<strong>in</strong>ess is a top priority: The new <strong>in</strong>stallation<br />
<strong>in</strong> Beauvais operates under clean-room conditions.<br />
The new clean<strong>in</strong>g <strong>in</strong>stallation was developed<br />
<strong>in</strong> co-operation with the Fisa<br />
Group, which has been mak<strong>in</strong>g a name<br />
for itself s<strong>in</strong>ce 1981 with the manufacture<br />
of ultrasonic clean<strong>in</strong>g mach<strong>in</strong>es for<br />
the automotive, aircraft and electronics<br />
<strong>in</strong>dustry, for the manufacturers of optical<br />
appliances and for medical eng<strong>in</strong>eer<strong>in</strong>g.<br />
The clean<strong>in</strong>g <strong>in</strong>stallation consists<br />
of a water-treatment facility, a<br />
turn<strong>in</strong>g unit, digital weigh<strong>in</strong>g scales, two<br />
ultrasonic r<strong>in</strong>s<strong>in</strong>g units (type 1 and 2), a<br />
dry<strong>in</strong>g oven, various secondary-treatment<br />
stages and a weld<strong>in</strong>g unit for<br />
packag<strong>in</strong>g bags, as well as the special<br />
monitor<strong>in</strong>g software.<br />
In order to avoid soil<strong>in</strong>g from external<br />
sources, "clean-room" conditions were<br />
created: All the technical equipment is<br />
enclosed <strong>in</strong> a k<strong>in</strong>d of cab<strong>in</strong> and the staff<br />
wear overalls and a head-cover<strong>in</strong>g.<br />
the composition of its m<strong>in</strong>eral salts<br />
plays a crucial part with regard to the<br />
trouble-free operation of the clean<strong>in</strong>g<br />
<strong>in</strong>stallation. A water-treatment facility,<br />
adapted to suit the exist<strong>in</strong>g tap-water,<br />
has therefore been <strong>in</strong>tegrated. This provides<br />
optimum conditions for co-ord<strong>in</strong>at<strong>in</strong>g<br />
the follow<strong>in</strong>g factors <strong>in</strong> the baths:<br />
water hardness, pH-value and concentration<br />
of detergent. Additional important<br />
parameters are composition of materials,<br />
temperature and duration of<br />
treatment, and ultrasonic frequency sett<strong>in</strong>g.<br />
Thanks to the experience which<br />
has already been ga<strong>in</strong>ed here, optimum<br />
sett<strong>in</strong>gs can be selected for any type of<br />
spr<strong>in</strong>g. This also means that the exchange<br />
of fluid required <strong>in</strong> the <strong>in</strong>stallation<br />
can be m<strong>in</strong>imized – a valuable contribution<br />
to the protection of the environment.<br />
The follow<strong>in</strong>g example shows the outstand<strong>in</strong>g<br />
results achieved:<br />
Customer requirements <strong>in</strong><br />
relation to cleanl<strong>in</strong>ess:<br />
• 4.00 milligrams of dirt particles per<br />
packag<strong>in</strong>g unit / 10 <strong>spr<strong>in</strong>gs</strong><br />
• former D6 <strong>in</strong>stallation us<strong>in</strong>g ultrasonics:<br />
2.42 milligrams of dirt particles<br />
per packag<strong>in</strong>g unit / 10 <strong>spr<strong>in</strong>gs</strong><br />
• new ultrasonic clean<strong>in</strong>g <strong>in</strong>stallation:<br />
0.52 milligrams of dirt particles per<br />
packag<strong>in</strong>g unit / 10 <strong>spr<strong>in</strong>gs</strong><br />
As the example shows, the customers'<br />
cleanl<strong>in</strong>ess requirements are exceeded<br />
by far. The <strong>in</strong>vestment made here is <strong>in</strong><br />
l<strong>in</strong>e with the standards of the<br />
SCHERDEL Group <strong>in</strong> relation to <strong>in</strong>novation<br />
and quality. It guarantees that<br />
the requirements for ISO 14001 certification,<br />
which the Beauvais factory has<br />
had s<strong>in</strong>ce December 2003, will cont<strong>in</strong>ue<br />
to be met <strong>in</strong> the future.<br />
